135. 如何通过 Rancher2 Terraform Provider 升级由 Rancher 管理的 k3s 集群

To do this import the k3s cluster into the Terraform configuration, then upgrade the cluster via Terraform.
要做到这一点，可以将 k3s 集群导入 Terraform 配置，然后通过 Terraform 升级集群。

Firstly, with the Rancher2 Terraform Provider configured (https://registry.terraform.io/providers/rancher/rancher2/latest/docs), define a rancher2_cluster resource for your k3s cluster, per the following example:
首先，在配置好 Rancher2 Terraform Provider（https://registry.terraform.io/providers/rancher/rancher2/latest/docs）后， 按照以下示例为你的 k3s 集群定义一个 rancher2_cluster 资源：

<span style="color:#000000"><span style="background-color:#ffffff"><span style="background-color:#f3f3f3">resource "rancher2_cluster" "k3s" { name = "k3s" }</span></span></span>

Then use the `terraform import` command to import the k3s cluster into your Terraform configuration (https://registry.terraform.io/providers/rancher/rancher2/latest/docs/resources/cluster#import), e.g.:
然后使用“terraform import”命令将 k3s 集群导入你的 Terraform 配置（https://registry.terraform.io/providers/rancher/rancher2/latest/docs/resources/cluster#import），例如：

<span style="color:#000000"><span style="background-color:#ffffff"><span style="background-color:#f3f3f3">terraform import rancher2_cluster.k3s c-m-h6xkkkvs</span></span></span>

Finally with the cluster imported, set the Kubernetes version in the k3s_config block to upgrade the cluster via a `terraform apply` operation, e.g.:
最后，在导入集群后，在 k3s_config 块中设置 Kubernetes 版本，通过“terraform 应用”操作升级集群，例如：

<span style="color:#000000"><span style="background-color:#ffffff"><span style="background-color:#f3f3f3">resource "rancher2_cluster" "k3s" { name = "k3s" k3s_config { version = "v1.23.7+k3s1" } }</span></span></span>
